6 Claims.

This invention relates to improvements in hair curling devices and moreparticularly to devices of this character for use in the cold set orroller method of hair curling.

It is commonly found that in the rolls and curls formed by thistreatment the hair ends become unset and loosely curled sooner than themain body of the roll, thereby necessitating a resetting of the entirecoiilure. Another difliculty experienced with cold wave rollers is thatthose in contemporary use may only be fixed in positions along the hairlength a full or half revolution apart and when close to the scalp oneposition often leaves a short uncurled length of hair while the nextsucceeding position abuts against the scalp and draws the hair sotightly as to cause extreme discomfort.

It is an object of the present invention to provide a cold set type haircurler which produces rolls more tightly coiled at the hair ends than inthe remaining length, thereby prolonging the efiectiveness of suchtreatment.

Another object of this invention is to provide a hair curler of thistype with which a more attractive style and otherwise more desirableeffect may be secured by forming at the ends of the hair tightly coiledringlets or rolls and in the remaining hair length curls ofsubstantially larger size.

Still another object of this invention is to provide such a hair curlerwhich may be readily fixed in selective and adjustable positions alongthe hair length.

Further objects and advantages reside in novel shapes and details ofconstruction, all of which will appear more fully in the course of thefollowing description.

In the accompanying drawings to which the description refers likenumerals are employed to designate like parts throughout the same,

. Fig. 1 is a side elevation of a curler embodying features of thepresent invention, partially broken for convenience in illustration andshowing in dotted outline a hank or skein of hair in an initial positionin the practice of the invention;

,Fig. 2 is a side elevation of the curler shown in Fig. 1, in which thedotted outline illustrates the hair roll at the completion of theoperation;

.Fig. 3 is a section taken along the line 33 of Fig. 2; and

Fig. 3A is a section similar to Fig. 3, showing another embodiment ofthe invention in which provision is made for selective positioning ofthe curler along the length of the hair.

Referring to Figs. 1 and 2, the invention comprises a spool-like memberS, a hair clamping 2. means or finger F hinged thereto, and slidably'mounted at one end of the member S a U-shaped locking means L.

The spool-like member S consists of a shank portion II circular incross-section and divergent from a relatively small diameter centrallyto a larger diameter at each end, and terminating in an enlargedcylindrical head portion I2 at one end and circular rim I3' ofSubstantially equal diameter at the other.

A means of clamping the shank I I to the skein of hair H wound thereonis provided by the finger element F, hinged to the shank II adjacent tothe head I2 by means of a pin I5. The finger F has a hollowsemi-cylindrical form and may include perforations as indicated by thereference numeral I6, although imperforate and various other designswill be equally operative and the illustration-in the drawings is merelyfor purposes of showing an operative reduction to practice. Said hingedconnection permits movement of the finger F from the open position(illustrated in Fig. 1) substantially perpendicular to the shank II to aclosed position (illustrated in Fig. 2) parallel to and partiallyenveloping the shank II. Two holes or bores I4 parallel to the axis ofspool member S are provided in the head portion I2 near its periphery toserve as guides for the locking means L, which is carried slidablytherein.

Said locking means L comprises a U-shaped' wire or spring formed into across head or connecting portion 22 and two straight and parallel legs20, spaced in relation to each other at the same distance as the guideholes I in the shank head I2. A short end portion 23 of each of the legs20 is bent outwardly at an angle so as to engage with the cylindricalhead I2 when the locking member L is retracted, thereby prevent ingcomplete withdrawal, while forward movement of the locking member L isarrested by engagement of the ends 23 with the protruding shank rim I3.The legs 20 are of somewhat greater length than the spool-like member Sso u that when the locking member L is in an advanced position with theend portions 23 in engagement with the rim I3 the cross head orconnecting portion 22 extend from the head portion I2 sufficiently toprovide a ready means of grasping for manipulation.

In the operation of the device hereinbefore described, the lockingmember L and the clamp or finger F are initially positioned openly asshown in Fig. 1. The ends of the hank or skein or hair, properlyprepared for setting, are then wound tightly upon the slender centralportion of the shank H for whatever length desired and the finger Fclamped in a closed position thereon. Continuation of the winding orrolling operation secures the finger F in its closed position and, byvirtue of its inclusion in the roll coils of substantially largerdiameter than the initial coils are formed. When the rolling operationis completed the locking member L is advanced to a closed position, theoutwardly extending ends 23 thereof serving to collect and confine thehair tightly against the spool member S and finger When the roll of hairhas dried and set, the

curler is removed by retracting the locking member L and unrolling thecurler suiiiciently to release the finger F and withdraw the spool-likemember S from the hair roll. In repeated use of this hair curlerdeformation of the legs 29 of the locking member L will inevitably occurdue to the strains of confining large rolls of hair against the shank H.The guide holes 54 are of such proportions and so placed as to realinethe legs 20 into their original shape upon each reciprocation of thelocking member L.

It is obvious that the end portion of the hair confined beneath theclamp or finger F will assume a much tighter or smaller curlcorresponding to the diameter of the slender central por tion of theshank H while that portion wound externally of the finger F will assumea looser coil corresponding to the larger diameter. With hair cold setin the manner described the tighter end curls will have a longer life ordurability, more nearly equal to that of the looser curls or waves inthe main body of the hair, thereby promoting a greater efficiency forsuch cold setting treatments. Also, the tighter end curls produced bythis invention are more easily concealed within end rolls and the like,while novel and attractive coiffures result from the combination ofsmall curls and ringlets in the hair ends and loose undulations in theremaining length of the hair.

Referring next to Fig. 3A, another embodiment of my invention isillustrated comprising substantially identical elements to thosepreviously described except that the enlarged cylindrical head L2 iscarried threadedly upon an extension H of the shank H, therebypermitting rotation of the shank with respect to the locking member L,its parallel legs 28 and the head portion 12' or vice versa.

The operation of this embodiment of my invention is likewise identicalwith that previously described with the exception of the lockingoperation. When the completed roll of hair is to be locked in positionagainst the head, it is important that the curler be secured'in such aposition that the entire hair length is rolled thereon yet that nounnecessary and painful pulling or drawing of the hair from the scalp isinduced. The threaded rotatable relation of the shank I! and the roll ofhair H coiled thereon to the looking member L provides a meansof-locking the curler in selected positions most desirable from thestandpoint of comfort and utility. This is eilected by holding thespool-like member S in the desired position against the scalp, meanwhilerotating the head portion l2 into a position most suitable for advancingthe locking member L. Removal of the curler from the hair upon drying,and the results attained by its use also correspond to those previouslydescribed.
